Pulsed Light Systems
target the Global Anti-Aging Market

Systems using high energy pulses of light (generated by laser or flshlamp) are used in
the field of medical wellness, the beauty / aesthetic area and cosmetic dermatology
with typical application in:





Removal of unwanted hair,
Removal of coloration changes,
Treatment of telangiectasis,
Treatment of acne
Skin rejuvenation

Large amount of clinical studies show the effectiveness of the method, especially in the
removal of unwanted hair.

Photorejuvenation currently ranks as one of the highest volume aesthetic procedures
in the world.

Today, the Intense Pulsed Light (IPL) technology, which uses high energy
flashlamps as sources of light, has replaced the laser devices in many applications.
IPL Devices
 Analysis of the market shows, that only
a few devices reach the current state
of the art
 Main disadvantages of current devices
are
 Approval as medical device missing
 Poor usability of the main system
 Change of the flashlamp too
complicated
 Poor usability of the handheld
applicator
 High level of pain for the patient
 High costs for the customer

Photoepilation: Removal of Hairs
High energy light pulses applied to the skin heat up the root of the hair (absorption of
energy in coloured hair) – the hair generating cells are destroyed. The optimum
wavelenght of light is between 650 nm – 1200 nm.
High densities of energy are required: 10 J/cm2 to 45 J/cm2.
Problem: The upper layers of the skin must not be heated!
